CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of co-pending (allowed) applicationSer. No. 12/774,955, filed May 6, 2010, and entitled DRY ADHESIVE BACKEDFLORING AND METHOD FOR MANUFACTURE, incorporated by reference herein inits entirety.

FIELD

This disclosure relates to the field of vinyl and other sheet flooringprovided in rolls. More particularly, this disclosure relates to sheetflooring having pre-applied dry adhesive and to the manufacture thereof.

BACKGROUND

Currently, most vinyl, rubber and other sheet flooring products areinstalled to a subfloor with wet adhesives. The wet adhesives areapplied to the subfloor as by use of a notched trowel. The appliedadhesives are allowed to cure for a prescribed amount of time, afterwhich the flooring material typically provided as a large roll is laidand then rolled with a weighted roller. This method can be timeconsuming, messy and with high moisture or high pH concrete subfloors,lead to adhesive failure. In addition, the adhesives typically havevolatile organic compounds. Thus, especially when applied in a hospitalsetting, the area must typically be evacuated for several days andmeasures taken to avoid exposure of adjacent areas to the volatiles.

In addition, especially in the hospital setting in which the floor isexposed to regular movement of a heavy bed on rollers, conventional wetadhesive applied floorings tend to disadvantageously creep, buckle, andotherwise deform after relatively short periods of time. In addition,the flooring industry has been having problems with regular processedglue adhesive in high moisture areas. Various mitigation methods havebeen attempted, but such methods are typically of high cost andgenerally unsatisfactory results.

Accordingly, improvement is desired in the field of sheet flooring, andin the installation of the same, especially in hospital settings and inhigh moisture areas, such as coastal areas and areas having relativelyhigh humidity levels.

The present disclosure advantageously enables the provision of rolledflooring having a sheet flooring material married to a double-sidedsheet adhesive in such a manner that the resulting flooring material issubstantially free of bubbles and wrinkles that would show through whenthe flooring material is installed on the subfloor. The disclosure alsoprovides methods and apparatus for manufacture of the flooring, andmethods for installation of the flooring.

SUMMARY

The above and other needs are met by a dry adhesive backed flooring forbeing installed in a flat orientation on a subfloor.

In a preferred embodiment, the flooring includes a sheet flooringmaterial and a double-sided sheet adhesive. The sheet flooring materialhas a first length, a first width, a decorative upper surface, and anopposite under surface. The double-sided sheet adhesive has a secondlength substantially corresponding to the first length, a second widthslightly less than but substantially corresponding to the first width,and first and second adhesive surfaces, the first adhesive surface beingadhesively secured to the under surface of the sheet flooring.

When the flooring is installed on the subfloor by contacting the secondadhesive surface to the subfloor, the installed flooring issubstantially free of bubbles and wrinkles and the second adhesivesurface sheet adhesive substantially permanently maintains the flooringadhered to the subfloor such that the flooring remains substantiallyflat as initially applied and does not significantly rise from thesubfloor, bubble or otherwise detach from the subfloor under normal useconditions for the flooring.

In another aspect, the disclosure relates to a method of manufacturing adry adhesive backed flooring for being installed in a flat orientationon a subfloor.

The method includes the steps of: providing a roll of a sheet flooringmaterial provided in a roll, the sheet flooring material having a firstlength, a first width, a decorative upper surface, and an opposite undersurface; providing a roll of a double-sided sheet adhesive, the sheetadhesive having a second length substantially corresponding to the firstlength, a second width slightly less than but substantiallycorresponding to the first width, and first and second adhesivesurfaces; and contacting the first adhesive surface to the under surfaceof the sheet flooring material to marry the sheet flooring material andthe sheet adhesive to yield the flooring.

In yet another aspect, the disclosure relates to apparatus for marryingflooring material in a roll form with a double-sided sheet adhesive inroll form having a first exposed adhesive surface for marrying with theflooring material and a second adhesive surface covered with a releaseliner to yield flooring in a roll form.

In a preferred embodiment, the apparatus includes a flooring materialsupport, a table, a flooring material position indicator, a sheetadhesive support, a sheet adhesive tensioning system, and a flooringsupport.

The flooring material support includes rollers for supporting a roll ofthe flooring material for unwinding of the roll and a computercontrolled positioning system that enables lateral adjustment of theposition of the roll of the flooring material.

The table includes a flat surface across which the flooring materialextends during operation of the apparatus to marry the flooring materialwith the sheet adhesive.

The flooring material position indicator detects the location of theedge of the flooring material relative to a location on the table andprovides corresponding signals to the computer controller of thepositioning system for comparing the location of the edge of theflooring material to a predetermined threshold and producing a signalcorresponding to the location of the edge of the flooring material. Whenthe signal indicates a location outside of the predetermined threshold,the positioning system adjusts the position of the flooring material sothat the edge thereof is returned to a location within the predeterminedthreshold.

The sheet adhesive support supports a roll of the sheet adhesive forunwinding of the roll. The sheet adhesive extends over the sheetadhesive tensioning system as it unrolls from the sheet adhesivesupport. The tensioning system is adjustable relative to the sheetadhesive support to maintain a substantially uniform and desired tensionon the sheet adhesive as it is unrolled from the sheet adhesive supportduring the manufacture of the flooring.

The flooring support includes a power driven shaft configured torotatably receive and snugly engage a core onto which the flooringrepresented by the married flooring material sheet and the sheetadhesive is rolled to provide a finished flooring material.

The apparatus functions to marry the flooring material and the sheetadhesive in such a manner that the resulting flooring material issubstantially free of bubbles and wrinkles that would show through whenthe flooring material is installed on a subfloor.

DETAILED DESCRIPTION

With reference to the drawings, the disclosure relates to a dry adhesivebacked flooring 10 that may be readily applied to a subfloor S, such asa concrete slab common to hospital floor structures, and to apparatusand methods for manufacturing and installing the flooring 10. Theflooring 10 is provided as a roll on a core C and includes a sheetflooring material 12 married to a double-sided sheet adhesive 14. Asdescribed more fully below, the sheet material 12 and the sheet adhesive14 are married in such a manner that the resulting flooring material 10is substantially free of bubbles and wrinkles that would show throughwhen the flooring material 10 is installed on the subfloor S.

The sheet flooring material 12 is a vinyl, rubber, or other sheetflooring product provided as a roll 16 (FIG. 3) It will be appreciatedthat the sheet material 12, and hence the flooring 10, may be providedin virtually any width, thickness, and length common to rolled sheetflooring. However, especially for hospital applications, the sheetmaterial 12 is provided in widths of from about 4 to about 7 feet and inlengths of up to about 100 feet. The sheet flooring material 12 has anupper decorative surface 18 opposite an underside surface 20.Conventionally, the underside surface 20 is somewhat roughened forbetter suitability with wet adhesives, such as latex adhesives,conventionally used to apply sheet flooring to a subfloor. It has beenobserved that the sheet material 12 for use in accordance with thedisclosure may have the underside surface 20 roughened, as isconventional, or the underside surface 20 may be smooth.

The double-sided sheet adhesive 14 is provided as a roll (FIG. 3) andincludes a scrim 22 having opposite adhesive surfaces 24 and 26. Thesheet adhesive 14 is provided on a roll having a length at least thelength of the roll of the flooring material 12 to which it is to beapplied. The lower adhesive surface 26 is covered by a release liner 28.Accordingly, when in its roll form, the adhesive 14 is rolled so thatthe release liner 28 provides the outermost surface of the roll and theadhesive surface 24 faces the release liner 28. A preferred double-sidedsheet adhesive is a double-sided polyacrylic adhesive sheet materialhaving a polyethylene terephthalate (PETP) scrim coated on both sideswith a thin and uniform layer of a polyacrylic-based transfer adhesiveand covered on one side by a silicon coated paper release liner. Thescrim 22 has a thickness of about 130 microns (5.12 mils) and theadhesive surfaces are applied in an amount of about 0.0029 to about0.0053 ounces per square inch.

The width of the roll of the sheet adhesive 14 substantially correspondsto the width of the roll of the flooring material 12, preferably beingslightly less such that the adhesive 14 does not extend beyond the sideedges of the flooring material 12. For example, for a roll of theflooring material 12 having a width of 6 feet (70 inches), the sheetadhesive 14 preferably has a width of about 69.5 inches, with the sheetadhesive 14 centered relative to the flooring material 12 to leave aspace of about 0.25 inches between the edge of the sheet adhesive 14 andthe edge of the flooring material 12.

It has unexpectedly been discovered that application of a scrimreinforced polyacrylic adhesive to vinyl or rubber flooring productsaccording to the disclosure yields a bond between the sheet adhesive andthe flooring and a bond between the subfloor and the sheet adhesive thatsubstantially permanently maintains the flooring adhered to thesubfloor, even when subjected to wet conditions. In this regard, theterminology “substantially permanently maintains” will be understood tomean that the flooring remains substantially flat as initially appliedand does not significantly rise from the subfloor, bubble or otherwisedetach from the subfloor under normal use conditions for the flooring.Normal use conditions means use conditions of the flooring common to theenvironment, such as rolling a bed thereon, walking upon, and the like,as to be distinguished from acts specifically designed to removeflooring, such as pulling upwardly thereon with substantial force. Inaddition, it has been unexpectedly observed that the flooring 10 may infact be applied to a wet concrete subfloor and that the sheet adhesive14 thereof substantially permanently maintains the flooring adjacent thesubfloor. Accordingly, the flooring 10 has been observed to beparticularly suitable for application in environments that experiencewet conditions, such as in basements, wash rooms and the like.

Without being bound by theory, it is believed that the scrim reinforcedpolyacrylic sheet adhesive 14 creates a barrier that resists water inthe concrete subfloor S from penetrating therethrough, and it has beenobserved that the scrim reinforced polyacrylic sheet adhesive 14substantially inhibits drawing or wicking of water. It is furtherbelieved that use of the sheet adhesive 14 to bond vinyl and rubberflooring or the like to concrete or other subfloor materials requirestwo bonds: one to the underside of the flooring material and one to thesubfloor. In this regard, manufacture of the flooring 10 as describedherein allows for the bond of the adhesive to the flooring material totake place in a controlled environment and in a precise manner thatavoids the formation of bubbles and wrinkles in the flooring material 10that would show through when the flooring 10 is installed on thesubfloor S.

In brief overview of the manufacture of the flooring 10, it has beendiscovered that marriage of the flooring material 12 and the sheetadhesive 14 in roll form requires attention to several key factors. Forexample, it has been observed that it is very difficult to marry theflooring material 12 and the sheet adhesive 14 while avoiding bubblesand wrinkles that would show through when applied or installed on theflooring 10. Vinyl and rubber sheet flooring products come from severaldifferent manufactures with varying compositions and widths, all ofwhich become factors in successful application. With some materialstemperature during application can also be a factor. Certain materialsrequire to be rolled surface face out and others face in.

For example, for softer compositions, width guides provided on theapparatus for the flooring material are pinched in until the material isslightly bowed (crimped between the guides until it rises off thetable). It has been discovered that this is advantageous so that whenthe tension from the winding application is in effect, the materialshrinks to fit in the guides. With regard to temperature, the ambienttemperature typically changes the flexibility of the flooring material12. Cold makes the material stiffer, and warmer weather makes thematerial more pliable and slower processing speeds may be indicated forthe colder materials. However, it is desirable to provide amanufacturing environment having a substantially uniform temperatureyear-round to minimize any temperature related effects. With regard toorientation, it is desirable to use of flooring materials with arelatively soft wear layer face out. Everything else is typically woundface in. Softness may be determined by depressing a thumbnail or smallblunt tool into the surface of the material. If it leaves andindentation that does not go away in a few seconds, it is consideredsoft and is rolled face out to protect the material.

It has been discovered that a preferred point to accomplish marriage ofthe sheet adhesive 14 to the flooring material 12 is right as it isbeing rolled up onto the core C to result in the flooring 10 beingsubstantially free of bubbles and wrinkles that would show through whenthe flooring material 10 is installed on the subfloor S. In addition,the flooring material 12 and the sheet adhesive 14 must be maintained ata desired angle so they consistently meet right at the marriage point.Also, having the sheet material 14 in a desired thickness and width isnecessary to provide proper coverage to the edges without allowingbleedthrough at the seams of the flooring during installation. Also,substantially even tension must be applied to the roll of the sheetadhesive as it unwinds to keep it running straight and wrinkle-free.

With reference now to FIGS. 3 and 4, there is shown a schematic of anapparatus 30 configured to desirably marry the sheet adhesive 14 withthe flooring material 12 to yield the flooring 10 so that it issubstantially free of bubbles and wrinkles that would show through whenthe flooring material 10 is installed on the subfloor S.

The marriage apparatus 30 includes a frame 32 onto which is located aflooring material support 34, a table 36, a flooring material positionindicator 38, a sheet adhesive support 40, a sheet adhesive tensioningsystem 42, a flooring support 44, and a weight system 46 for bearingagainst the flooring support 44. The apparatus 30 may further include aweighted roller 48 and a lateral adjustment roller 50.

The apparatus 30 is configured to provide the flooring 10 in a rolledorientation with the decorative surface 18 facing inward. This isdesirable to protect the decorative surface 18. However, as describedbelow in connection with FIG. 5, apparatus may be configured to providethe flooring 10 in a rolled orientation with the decorative surface 18facing outward.

The frame 32 provides a sturdy support for mounting and positioning thevarious components of the apparatus 30, and may be provided as by weldedsteel construction. The flooring material support 34 is located at afirst end of the frame 32 and includes a pair of support rollers 52 ontowhich the roll 16 of the sheet flooring material 12 is placed, with thematerial 12 unrolling from the bottom of the roll 16 with the roll 16rotating counterclockwise on the support rollers 52. The support rollers52 are mounted on a lateral positioning system 54 that is movablelaterally, e.g., left or right, relative to the frame 32 and the table36 on the frame 32. Movement of the lateral positioning system 54 iscontrolled as by a computer controller 56 associated with thepositioning system 54 in response to feedback from the flooring materialposition indicator 38. The controller 56 may communicate with thepositioning system 54 and the position indicator 38 as by wire orwireless interface. The lateral positioning system 54 may be provided asby an electrically powered wheeled member 54 a laterally movable on atrack 54 b as by an electric drive motor controlled by the computercontroller 56.

The table 34 provides a large flat surface across which the flooringmaterial 12 is extended to enable the width of the flooring material 12to be aligned with the sheet adhesive 14. In this regard, the table 34includes a flat surface 60 along the longitudinal sides is disposed apair of width guides 62. The table 34 includes a roller 64 located atthe distal end of the table 34 so as to enable the flooring material 12to be directed from the table 34 to the flooring support 44 at a desiredangle. In this regard, as explained below, it has been discovered that adesired angle of the flooring material 12 relative to the sheet adhesive14 is desired to enable satisfactory marriage of the flooring material12 and the sheet adhesive 14 to provide the flooring 10. The weightedroller 48 may be provided above the table 30 if desired to be positionedto bear against the flooring material 12 if needed to maintain tensionin the material 12, such as when the material 12 is substantially at theend of the roll.

The flooring material position indicator 38 may be provided as by anelectrical eye or other sensor suitable for detecting the location ofthe edge of the flooring material 12 relative to one of the guides 62and for providing corresponding signals to the computer controller 56for comparing the location of the edge of the flooring material 12 to apredetermined threshold. If the location of the edge of the flooringmaterial 12 exceeds the threshold, information in this regard from theindicator 38 is utilized by the computer controller 56 to generate asignal to the lateral positioning system 54 that results in thepositioning system 54 adjusting the position of the flooring material 14so that the edge thereof is returned to a location within thepredetermined threshold. For example, the wheeled member 54 a will movealong the track 54 a in a desired direction and a desired amount toreposition the support rollers 52, and hence the roll 16 of the flooringmaterial 14, a desired amount. The position indicator 38 preferablyupdates the location information substantially continuously.

The lateral adjustment roller 50 may also be utilized in conjunctionwith the position indicator 38 to adjust the location of the edge of theflooring material 12. For example, the roller 50 is located adjacent thedistal end of the table 32 and may be configured to enable applicationof non-uniform pressure onto the material 12 to urge the material sothat it moves laterally one way or the other. The roller 50 may becomputer controlled utilizing information from the position indicator 38in the manner of the positioning system 54.

The sheet adhesive support 40 is provided as by an air expandablebladder shaft 66 configured to rotatably receive and to expand to snuglyengage the roll of the sheet adhesive material 14 as it unrolls. Thesheet adhesive support 40 is located downline from the flooring materialsupport 34, and upline from the flooring support 44. The sheet adhesivetensioning system 42 is provided as by a pair of laterally spaced bars68 over which the sheet adhesive 14 is passed. The bars 68 areindependently and vertically adjustable relative to the support 40 andare adjusted to positions to maintain a substantially uniform anddesired tension on the sheet adhesive 14 as it is unrolled during themanufacture of the flooring 10.

The flooring support 44 is provided as by a power driven and airexpandable bladder shaft 70 configured to rotatably receive and toexpand to snugly engage the core C onto which the flooring representedby the married flooring material sheet 12 and the sheet adhesive 14, isrolled to provide the finished flooring material 10. The flooringsupport 44 is located downline of the sheet adhesive support 40. Theshaft 70 may be rotated at a desired speed as by an electrical motor.

The weight system 46 is configured to bear against the outer surface ofthe enlarging roll of the flooring 10 as the flooring 10 ismanufactured. This is desirable to maintain a desirably tight winding ofthe roll of the flooring 10. The weight system 46 may include a steelbar 72 pivotally mounted to the frame 32 adjacent the roller 64 andhaving a roller 74 located at a distal end thereof for engaging the rollof the flooring 10.

As shown in FIG. 3, the apparatus 30 is configured so that the flooringmaterial 12 unrolls from the roll 16 and onto the table 32 to asubstantially flat orientation, extending in this manner to the roller64. The flooring material 12 curves over the roller 64 and downward tothe core C mounted on the shaft 70 of the flooring support 44. The sheetadhesive 14 unrolls from a location in-between the roll 16 and the corec, and passes over the sheet adhesive tensioning system 42 and to thecore C. In this regard, it has been observed to be beneficial tomaintaining tension of the sheet adhesive 14 to maintain the angle ofthe sheet 14 approaching the tensioning system 42 at an angle A of fromabout 30 to about 60 degrees, and maintaining the angle between theleading and the trailing one of the rollers 62 at an angle B of fromabout 0 to about −20 degrees.

The confluence of the flooring material 12 and the sheet adhesive 14 atthe core C provides a marriage point MP of the flooring material 12 andthe sheet adhesive 14. The marriage point MP is defined substantially atthe core C, it being understood that the marriage point MP, whileinitially at the core C, will radially migrate from the core Ccorresponding to the thickness of the roll of the flooring 10 as theroll of the flooring 10 enlarges. In this regard, it has been observedthat it is advantageous to maintain the angle between the flooringmaterial 12 and the sheet adhesive 14 approaching the marriage point MPat an angle C of from about 65 degrees to about 85 degrees, mostpreferably about 78 degrees.

In operation of the apparatus 30 to marry the flooring material 12 andthe sheet adhesive 14 to provide the flooring 10, the flooring material12 and the sheet adhesive 14 are each located on the apparatus 30 asdescribed and initially each secured to the core C located on thepowered shaft as by tape or the like. Then, the powered shaft 70 isrotated at a desired rotational speed, initially of about 4 rpm, rampingup to about 25 rpm, until the end of the roll of the flooring material12 is approached, at which time the speed is slowed. As will beappreciated, the powered shaft 70 serves to appropriately unwind therolls of the flooring material 12 and the sheet adhesive 14, with theflooring material support 34 and the flooring material positionindicator 38 operating as described to maintain the flooring material 12in alignment with the sheet adhesive 14, and the sheet adhesivetensioning system 42 maintaining desired tension of the sheet adhesive14. In this manner, the apparatus 30 functions to marry the flooringmaterial 12 and the sheet adhesive 14 (with the underside surface 20married to the adhesive surface 24) in such a manner that the resultingflooring material 10 is substantially free of bubbles and wrinkles thatwould show through when the flooring material 10 is installed on thesubfloor S.

With reference now to FIG. 5, there is shown an apparatus 80 configuredfor use with the flooring material 12, when it is of a type with arelatively soft wear layer face out, and configured to roll the material12 face out to protect the material. The apparatus 80 may include thesame components as the apparatus 30, such components bearing the samereference numerals as in the apparatus 30, except an additionalcomponent in the nature of a nip 82 provided by opposed rollers 84 and86. In this regard, the nip 82 provides a location for a new marriagepoint MP′, the new location being remote from the core C and closer tothe roll of the sheet adhesive 14. It has been observed that a slightdecrease of the angle at which the flooring material 12 and the sheetadhesive 14 meet at the new marriage point MP′, with an angle C′ of fromabout 60 degrees to about 80 degrees, most preferably about 70 degrees.The apparatus 80 may be operated in substantially the same manner as theapparatus 30 to provide the flooring 10 which is substantially free ofbubbles and wrinkles that would show through when the flooring material10 is installed on the subfloor S.

The flooring 10 according to the disclosure is substantially easier andless time consuming to install as compared to conventional wet adhesiveapplied rolled flooring. For example, the flooring 10 may be applied asby simply unrolling the flooring 10 over the subfloor S, while removingthe release liner 28 so that the adhesive surface 26 faces and overliesthe subfloor S. Next, a heavy roller or the like is rolled over the thusinstalled flooring 10, rendering the flooring 10 in an installed state,with the flooring 10 being immediately available for use, includingheavy foot traffic, rolling of a bed or the like, with no furthertreatment or curing of the adhesive being needed. The subfloor S mayeven be wet without negatively impacting installation, however, it ispreferred that it not have an appreciable dirt, dust, or other looseparticulate matter thereon.

Another advantage of the flooring 10 is that the sheet adhesive 14 issubstantially free of any volatile organic compounds or the like, suchthat the area into which the flooring 10 is installed may be immediatelyoccupied. In addition, it has been observed that the flooring 10 hasgreatly enhanced resistance to bubbling, rising, or the like as iscommon to conventionally adhered flooring, and due to this, is able tolast substantially longer, especially in the hospital environment, wherethe floor is often exposed to moisture and heavy use as by the rollingof beds thereon. In this regard, the flooring 10 once applied issubstantially permanently maintained adjacent the subfloor by the sheetadhesive 14 while avoiding bubbling, rising, and the like. In addition,the installed flooring 10 has an aesthetically pleasing appearance, andis substantially free of bubbles and wrinkles.
